A LucidLink Filespace provides multiple configuration parameters applicable both locally or globally across all clients participating in the global namespace.
While in most circumstances the defaults are sufficient, it is important to understand the many configurable options built into our service.
The control panel enables the configuring of your frequently administered Filespace settings including your Users, Shares, Local and Global operating system client settings.
Managing Filespace Users, Filespace Groups, administering their Shares, and setting up point-in-time Snapshots are covered in separate knowledge base articles. In this article, we will focus specifically on settings.
Locate the LucidLink
logo within the Taskbar to access the control panel. Type your password and select Open control panel.
Each setting option within the control panel is accompanied by an information tooltip to provide guidance and a detailed explanation of the setting's function.
Typical operations are:
- Set the location your Filespace is mounted
- Increase or decrease cache size
- Tune your parallel upload and download connection counts
- Apply download and upload transfer rates to suit available bandwidth
- Adjust file locking file extension types
Please reach out to LucidLink Support for guidance and make changes carefully as the performance of your Filespace or network could be affected by incorrectly set parameters.
When logged in as Root you will have access to the full control panel including Users, Shares, along with Local and Global settings.
Global settings will be used as defaults for all machines connecting to this Filespace. Changing some settings may require machines to reconnect to the Filespace in order to take effect.
Note that users may still override their local settings.
Logged in as a regular User will present you with options to change only the local LucidLink client settings for your current machine, not Global settings or Users and Shares.
Local settings will affect this machine only. Changing some settings may require a reconnect to the Filespace in order to take effect.
Advanced Filespace configuration
Lucid config command-line interface provides far more detailed administration of your Filespace than what is available in the control panel.
Make changes carefully as the performance of your Filespace or network could be affected by incorrectly set parameters.
